Esperanza Montes Perez, right, listens as her son Miguel Perez Jr. addresses the media via cellphone from Mexico after he was deported on Sunday, at O'Hare International Airport on March 26, 2018. Perez, Jr. is a green card veteran who served two tours of duty in Afghanistan, then later served time in prison on a felony drug conviction.

Miguel Perez Jr. is one of many legal permanent residents who have served in the U.S. military, then been confronted with the possibility of deportation to their native countries after committing a crime.
